APPARATUS FOR coouue MASH.

SPECIFICATION forming part of Letters Patent No, 292,885, dated February 5, 1834.

Application filed November 2 1883. (N0 model.)

To allwhom it may concern:

Be it known that I, JACOB IVooLxcn, of Peoria, in the county of Peoria, in the State of Illinois, have invented an Improved Apparatus for Cooling Mash; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to.

the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which Figure 1 represents a plan view of the apparatus; Fig. 2, a vertical section.

The object of this invention is the construction of apparatus for cooling mash preparatory to its fermentation in the manufacture of spirits that shall be in a high degree economical in its use of water, and that shall also employ the lTlllllllllll'llnumber of ruashpuinps. To effect this purpose I have devised the following construction:

F F are two tubspreferably oval in plan-- in each of which is a coil of copper pipe. The head of the coil U in the tub F is connected with the pump 13 by a suitable pipe, 0, while its tail is joined by the pipe 0" to'thc head of the coil 0 The tail of this latter coil 0 communicates with the fermenting-tubs, or to a spout leading thereto. The suction-pipe 0 extending from the pump B to the mash-re ceiver A enables said pump to force the mash from said receiver through both the coils G G to the fermenting tub or tubs T. The tubs F F being filled with water, cool as can be obtained, the coils (J C, and therefore the mash flowing through them, are brought to the desired low temperature. The means by which these tubs F F are kept constantly filled with cool water-and no water is lost until it has taken as much heat as possible-is as follows:

E is a pipe, terminating at the bottom of the tub F in a T, by which a constant stream of cold water is admitted and directed horizontally toward the coils i From the upper edge of the tub F is an overflow-pipe, FF, which runs to the bottom of the tub F, and is there supplied with a T-pipe, E similar to' rected to the waste-drain, or wherever else dosired.

overflow from the tub F and surround the coil C in the tub F, the hot mash passing through said coil is cooled down to approximately the temperature of this lukewarm water in the tub F before it gets to the coil 0 and is cooled therein to the desired degree. It is therefore evident that this construction effects a great saving in the amount of water used, not only for the reason just described, but for the increased exposed surface which is given the water by being contained in two open tubsinstead of one alone. The increased exposed surface permits increased evaporation of the water, and thereby keeps it somewhat cooler. By having the hottest mash cooled in the warmed water of the tub F, the joints, elbows, and pipes themselves of the coils 0 C are saved from the strain which would ensue from the unequal expansion consequent upon their con taining an extremely hot liquid, but being immersed in cold water.

Although I have described but two tubs, F F, I design using in the same waya series of several, so that when the water is permitted at last to escape from the tub containing the first coil, 0 the temperature of said water may not be but a degree or two cooler than the mash entering the coil.

Since the coils C G are the continuation of the same pipe, a single pump, B, serves to force the mash through them both, when if they were disconnected two pumps would be necessary. The decreased amount of cold water suppliedto the tubs F F enables me to use a comparatively small pump to supply the same.

What I claim as my invention, and for which I desire Letters Patent, is-

1. In a mash-cooling apparatus, two or more IOO tubs, only one of which is adapted to receive fresh supplies of cold water, each of the others being filled from the overflow of the tub before it, in combination with a coil of pipe in each tub, and connections whereby a continuous stream of mash may be pumped through them all, substantially as shown and described.

2. The tub F, having water-supply pipe E and overflow E terminating at the bottom of the tub F, in combination with said tub F and the coils O 0 continuous from one to the other, and having suitable supply-pump, substantially as and for the purpose specified.

8. The pump B, having suction pipe C,

coils C 0, having connecting-pipes C C, and I 5 exit-pipe O, in combination with the tubs F F, supply-pipe E, having a T-shaped discharge end, E, at the bottom of the said tub F, overflow pipe E having a T discharge end, E", and the overflow-pipe O, substantially 20 as and for the purpose set forth.

In testimony that I claim the foregoing invention I have hereunto set my hand this 17 th day of November, 1883.

. I JACOB XVOOLNER.
